ABSTRACT
<p><b>OBJECTIVE</b>To assess occlusal balance of normal occlusion in intercuspal position with maximal bite force.</p><p><b>METHODS</b>Maximal bite force was recorded in intercuspal position by use of T-Scan II system from 123 subjects with normal intact dentitions. Occlusal balance of normal occlusion was quantitatively analyzed from center of force, percentage of bite force, and occlusal contacts.</p><p><b>RESULTS</b>The relative position of the center of bite force, the difference in bilateral force percentage, and unsymmetrical coefficient followed normal distributions. The 95% reference ranges for corresponding testing items were -6.60 to 6.68 mm, -15.50% to 12.10%, and 0.65 to 1.39. There was no statistic difference (P = 0.915) in occlusal contacts between left and right sides. The 98.4% of normal occlusion subjects had the center of bite force locating in posterior region of dentition when biting with maximal force in intercuspal position.</p><p><b>CONCLUSIONS</b>Occlusal balance could be evaluated by T-Scan II system. Occlusion of normal subjects biting with maximal force was stable and bilaterally balanced in intercuspal position.</p>
